SYMPTOM
The module appears completely "dead".
None of the LEDs is lit.
The module is working correctly, the
channel LEDs and relays switch on but
the valves connected to the outputs are
all inactive.
One or more channel LEDs (
on the front panel of the module blink
green continuously.
One or more channel LEDs (
on the front panel of the module blink
yellow continuously.
One or more channel LEDs (
the front panel of the module blink red
continuously.
A transmitter is in the "test" mode
but the module fails to switch on any
relay, even though the LED of the
active antenna indicates that the radio
commands are being received.
The "power" LED ( 2 Fig.1) is blinking.
A transmitter is in the "test" mode but
the module fails to switch on any relay,
the LED of the active antenna remains
steadily lit green, not indicating any
reception of commands via radio.

TROUBLESHOOTING
PROBABLE CAUSE
There is no power.
The thermal fuse on the incoming power
line has tripped.
The fuse protecting the loads has
blown.
The device is signalling a fault because it
3 Fig. 1)
has detected an error in the temperature
probe of the
thermostat or chronostat transmitter.
The device is signalling a fault because

it has detected the thermostat or
chronostat transmitter batteries to be
running low.
3 Fig. 1) The channels in question are in an
"alarm status" due to the absence of
radio communication.
The commands emitted by the
transmitter are being correctly received
but do not correspond to any of the
addresses memorised in the relay
module.
There is a problem in communication
with the active antenna or other
modules connected in the chain.
The signals received are too weak
to enable correct decoding of the
commands.
Check the device power supply.
Switch off the device. Wait at least 15
minutes and then switch it back on (see
section on "Electrical connections").
Make sure that both the mains
and auxiliary power supplies are
disconnected,
integrity of fuse (Fig. 2) and, if
necessary, replace it with a new fuse
of the same type and rating (also see
section on "Electrical connections").
Check the probe of the transmitter
and, if present, the jumper for selecting
between the internal and external
probe.
Carefully read the instructions of the
transmitters for further information.
Replace
transmitters concerned. Carefully read
the instructions of the transmitters for
further information.
Check the radio communication using
the "test" function on the transmitter.
Assess whether the devices need to be
moved away from metal shields or a
"repeater" needs to be installed.
Carry out the "self-learning" procedure
as directed in the section "Configuring
the System" for the channel you wish to
associate with the transmitter.
Check that the data cables are plugged
in correctly. The cable connected to the
"SIGNAL IN" socket must lead in from
the active antenna, whereas the cable
connected to the "SIGNAL OUT" socket
must lead out to another 8-channel relay
module.
Assess whether the devices need to be
moved away from metal shields or a
"repeater" needs to be installed.
